To all whom it may con/cern:

Be it known that I, ALVA J. FISHER, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements in Ladlesfor Casting Car-VVheels, of which the following' is a specication.

My invention relates to that class of ladies for casting car-wheelswhich discharge the molten metal through an opening in the bottom 5 andmy object in this connection' is to generally improve upon the ladles atpresent in use by providing Aa more reliable, strong, and durablestopper-adjustiug means and a shield or guard to protect certain partsof the device from the molten metal splattered inl the manipulation ofthe ladle, this shield or guard thereby -expediting the work.

Other objects of the invention will hereinafter appear and be pointedout in appended claims, and in order that the invention may be fullyunderstood I will proceed to describe it with reference to theaccompanying drawings, in which- Figure 1 represents a detail verticalsection ct' the upper partof a ladle embodying my invention. Fig. 2 isatop plan view of the same. Fig. 3 is a side elevation showing thestopperoperating mechanism. Fig. 4 is a horizontal section taken justabove the lever 6 in Fig. 3. Fig. 5 is a detailed elevation of thetrunnionbearing.

In said drawings, 1 designates the usual cylindrical'ladle, providedwith a lining 2 and a discharge-nozzle 3, arranged eccentrically of itscenter (see Fig. 2) and provided with a concave or segmental seat 4 inits upper end.

5 designates a slide-rest provided vin Aits outer face with alongitudinal dovetail groove G and bolted, as at V7, in a verticalposition to the ladle adjacent to the nozzle 3.l Q

8 designates a slide dovetailed in the groove 6 and provided at itsupper end with a horizontal head9, extending radially of the ladle, andprovided with a shield or hood for preventing splattered metal fromentering the dovetail groove, and thereby rendering impossible theproper manipulation of the slide, the improper manipulation of which isdestructive to` the car-wheel being cast. This shield or hood consistsof the side wings 10, diverging ldownwardly from opposite sides of thehead 9 and bifurcated, as at 1l, to accom- Patent No. 633,991, datedOctober 3, 1899.

modate the wall of the ladle. It also comprises the downwardly andinwardly sloping wing 12, which projects down into the ladle, and ispreferably formed at its upper end and outer side with a downwardly andoutwardly sloping wall 13, which tends to deflect inward any moltenmetal which has splattered up betweenthe wing 12 and the lining ot theladle. By means of this shield or hood it will be seen that it 7ispractically impossible for molten Inetal to enter the groove 6, andthereby interfere with the proper manipulation of the slide. If themetal should enter said groove and sowould be impossible to check thedow of metal .from the ladle at'the exact instant necessary, and wouldthereby result in a ruined or defective car-wheel. Near its outer endthe head 9 is provided with a vertical stud 14 and in radial alinementand inward of the same with a second stud 15.n

l16 designates a plate provided with a hole 17, engaging stud 14, and aslot 1S, engagingv stud 15, in order that said/plate 16 may be laterallyadjusted as required. The upper ends of these studs 14 and 15 areengaged by clamping-nuts 19 and 20, respectively, whereby plate 16 isclamped in the required position. The inner end of said plate isbifurcated, as at 21, and bent to form bearing-cavities at op positesides of the bifurcation and justinward of the latteris provided with avertical stud 22, engaged at its upper end by a nut 23, Whichsecuresplate 24 in position. j This plate 24 is bifurcated at its inner end, asat 25, and said end is bent to form downwardly-disposedbearing-cavities. It is also bent downward at its rear end to form thefulcrum or bearingpoint 26, which rests upon plate 16, thereby givingclamping-nut 23 a leverage in order that plate 24 may be clamped tightlyupon the right sleeve 28, the sleeve extending through the registeringbifurcations 21 and 25, with plates 16 and 24.

Thestopper of the ladle consists of the head 29, of any suitablematerial and at its lower side of hemispherical form in order that itmay effectually close the ,discharge-nozzle when seated in recess 4, asindicated by dotted lines in Fig. 3.` This stopper is secured lidify atits lower end, it is obvious ythat it oppositely-projecting trunnions 27of the up-y its trunnions ttiu g in bearings formed in the` in anysuitable manner upon the lower end of rod 30, extending up through thesleeve 2S and engaged at its upper end by the clamping-nut 3l, andsurrounding said rod is a protective covering 32, which prevents the rodgetting so hot that it will bend'. This covering connects with thestopper 29 at its lower end and at its upper end is embraced by a cap33, and between said cap and the lower end of the sleeve are washers 34.In practice the plate 16 is adjusted to dispose the sleeve 28 verticallyover the center of the discharge-y nozzle, so that when the stopper isclamped to the perpendicular sleeve it will close said nozzle, providedthe slide occupies its depressed position, asshown in the drawings. Asfrequently happens, however, the rod 30 may not be perfectlystraight,therefore throwing the head 29 of the stopper out of line withthe upper end of rod 30 and the discharge-nozzle, With the result thatan imperfect stoppage of the latter is effected. To correct this evil,the clamping-nut 23 is loosened and the trunnions 27 turned in theirbearing to dispose the sleeve 2S vat such an angle that the head 29 ofthe stopper will accurately iit in the recess 4 and effectually closethe dischargenozzle, or if the bend of the rod 3() is of such characterthat a lateral adjustment is necessary such adjustment can be effectedby loosening nut 2O and swinging plate 1G to the1 right or left, as thecase may be, on the pivotpin 14E, slot 1S engaging pin l5, permittingthis adjustment to be made. If the bend in the rod should be neitherdirectly inward nor lateral, but between the two, then it would benecessary to adjust the sleeve 2S in addition to the adjustment of plate16. It will therefore he seen that this construction gives practically auniversal adjustment of the stopper. In order to manipulate the slideand the stopper connected thereto, I provide the following construction:35 designates a pitnian which is pivot-ally mounted at its upper endupon a stud 36, projecting from the slide, and at its lower end upon apin or bolt 37, carried at the front end of a lever 38. Said lever isfulcrumed upon a stud or bolt 39, projecting from the slide-rest, and isprovided with a handle 40, preferably detachable. By depressing saidhandle through the medium of the pitman 35 the slide and stopper areinstantly raised and the molten metal permitted to flow out of the ladlethrough the discharge nozzle thereof and into the mold. (Not shown.)When the handle is released, the slide gravitates back to its originalposition, and this gravitative action can beldepended upon, owing to thefact that thereis no possible chance for the molten metal obtainingaccess to the groove in which said slot operates.

The stoppercarrying rod 30 is preferably constructed of wrought-iron,and a protective covering for the same is made of a compositionconsisting of molding-sand, silica-sand, and lire-clay, preferably fourparts each of the molding and silica sand and one-fifth part lire-clay,dampened to render it plastic. This composition in practice is found toanswer admirably. The ladle is constructed of steel, by preference, andthe slide and resttherefor of cast-iron. It is to be understood,however, that I do not restrict myself to the use of any material orcompositions of materials except as hereinafter indicated in the claims.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is*
